I would like to connect a battery to vBAT Pin for my Nucleo STM32L476RG.
I'm wondering if I should remove SB45 resistor or not.
If anyone could tell me what's the correct steps to build a vBAT backup circuitry.
Thank you in advance.
Hello paker earth
I have moved your thread to the STM32 MCUs Forum where product-related questions should be posted.
Yes. Remove SB45 and connect battery to pin 33 of CN7.
You might want to have a look at the L4 DISCO, it has a CR2032 battery holder too.
Hi paker earth,
Yes ,you have to remove SB45 as said waclawek.jan.
